The standard initial management for AOSD includes conventional corticosteroids and disease-modifying antirheumatic drugs. In cases that are resistant to these treatments, additional therapeutic options such as immunosuppressants, biologics, and other alternative treatments may be considered. Yet, a significant proportion of patients remain unresponsive to these therapeutic interventions. Herein, a case is reported involving a patient with AOSD who had persistent pruritic lesions that did not respond to conventional therapy, but were alleviated with Janus kinase inhibitors (JAKi), namely baricitinib and upadacitinib. The objective is to expand the number of refractory AOSD cases treated with JAKi in clinical practice. Another aim is to offer potentially effective therapeutic options for AOSD patients who experience persistent pruritus.</p><h3 data-test=\"abstract-sub-heading\">Methods</h3><p>A case was reported involving AOSD characterized by persistent pruritic lesions that failed to respond to conventional treatment, but showed favorable outcomes with JAKi therapy. An analysis of the PubMed literature was performed to assess the medication’s efficacy and explore possible mechanisms.</p><h3 data-test=\"abstract-sub-heading\">Results</h3><p>The present case study is one of the few documented instances exploring the use of JAKi for treating AOSD, aligning with previously published research. After initiating JAKi therapy, the patient exhibited significant improvement in symptoms, most notably a reduction in persistent pruritus. Additionally, there was a substantial decrease in the patient’s glucocorticoid dosage. Aside from minor renal function anomalies, no adverse reactions were observed.</p><h3 data-test=\"abstract-sub-heading\">Conclusions</h3><p>The present case illustrates that JAKi can provide rapid and sustained clinical improvement in patients with AOSD, especially those who have not responded to conventional treatment, and they have the ability to alleviate persistent itching.

All related registration information disclosed on the CDE website, including posted time, drug classification, dosing formula, indications, trial design, and trial status, were summarized and analyzed. A total of 5336 early-phase clinical trials were identified. The quantity and growth rate of early-phase clinical trials have increased substantially each year. Chemical drugs accounted for the largest proportion of early-phase clinical trials, although it dropped from 85.7% in 2013 to 59.5% in 2022. Moreover, the number of oncology drugs has increased yearly, accounting for 49.2% of all early-phase clinical trials in 2022. We can conclude that during 2013–2022, the development of early-phase clinical trials has progressed due to government support and advanced development techniques. To enhance the efficiency and success rate of early-phase clinical trials in the future, it is necessary to acquire advanced technical support and improve standardized supervision systems.</p>","PeriodicalId":11373,"journal":{"name":"Drugs in R & D","volume":"56 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-09-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142217323","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

There were 24 participants in both the fed study and the fasted study. Following a 7-day washout period before receiving the alternative formulation, eligible research participants were randomly assigned (1:1) to receive a single dosage of either the reference formulation or the test formulation.

For the bioequivalence assessment in the fed trial, the key PK parameters comparison between the reference and test formulations revealed that the GMR (90% CI) values for AUC<sub>0–<i>t</i></sub>, <i>C</i><sub>max</sub>, and AUC<sub>0–∞</sub> were 103.00% (100.94–105.11%), 101.90% (99.63–104.22%), and 102.99% (100.87–105.16%), respectively. The geometric mean ratios (GMRs) for the primary pharmacokinetic parameters (<i>C</i><sub>max</sub>, AUC<sub>0–72</sub>, and AUC<sub>0–∞</sub>) between the two formulations and the corresponding 90% confidence intervals (CIs) were all within the range of 80.00–125.00% for both the fasting and fed states.
